A bit of an exaggeration, Betamax gave a better picture but the difference
was subtle, so subtle you couldn't even tell the difference unless you had a
very good and expensive TV, and there are more important technical
considerations. When VHS first cane out it could record 2 hours on one
cassette, Betamax could only handle one, by the time Betamax cane out with
2 hours VHS was up to 4 and very soon after that 6 hour. Remember this was a
time when blank cassettes or either type were very expensive, about $20 each,
and that was in 1980 dollars.
